Summary
Revision cochlear implant (CI) surgery is common in children, with hard device failure, often due to head trauma, being the primary reason. Auditory performance typically recovers within a year post-revision.
Area of Science:
- Pediatric Otolaryngology
- Biomedical Engineering
- Auditory Implants
Background:
- Cochlear implantation (CI) is a vital auditory prosthetic for children with severe to profound hearing loss.
- Revision surgeries for pediatric cochlear implants (CIs) are necessary but their incidence and causes require detailed examination.
Purpose of the Study:
- To determine the incidence and indications for revision cochlear implant (CI) surgery in pediatric recipients.
- To analyze the pattern of events leading to revision CI surgery in children.
Main Methods:
- A retrospective case review was conducted across two tertiary pediatric CI centers.
- Data collected included reasons for revision, surgical outcomes, complications, auditory performance, and device analyses for pediatric CI patients undergoing revision.
Main Results:
- 11.2% of pediatric CI operations (107 of 952) required revision surgery.
- Hard device failure (46%) was the most frequent indication, often linked to head trauma (41% of hard failures).
- Auditory performance generally returned to or exceeded pre-revision levels within 6-12 months post-surgery.
Conclusions:
- Revision CI surgery is a significant consideration in pediatric CI care, with device failure being a primary driver.
- Head trauma is a notable factor contributing to hard device failure in pediatric CIs.
- Counseling families on expected auditory performance recovery post-revision is crucial, acknowledging potential variability.
